Trip Overview 

The South Fork of the Flathead is known in the fly fishing world as the Mecca for dry-fly cutthroat fishing. Located in the 1.5 million-acre Bob Marshall Wilderness, America’s first ever designated wilderness area, the South Fork is formed from the junction of Danaher Creek and Young’s Creek. From here, it runs 45 miles due north, fed by dozens of small tributaries, where it exits the wilderness near Spotted Bear Ranger Station. This trip completely transects the wilderness area from south to north, right through the deepest, most remote area of the “Bob."

Lodging Details
When you arrive in camp at the end of each day, spacious two-person tents are already pitched, camp is set up, and drinks are ready. A hearty and delicious streamside dinner will provide the perfect end to a day in the wilderness. Stare into the campfire, enjoy a glass of wine, think about the rises of the day, or the “one that got away,” the hook-ups to come in the morning. Swap stories with your friends and watch the last flicker of sunset slip below the mountaintops. A tent, cots and ThermaRest pads are included. Dry bags are provided for each client, allowing you to pack your gear in waterproof bags and keep your clothing safe and dry on the river.

Food and Beverages
Appetizers and beverages await your arrival each evening after a full day on the river. Enjoy hearty, “camp-style” Western meals featuring fresh salads, entrees such as Bison tacos or rib-eye steaks grilled over an open fire, and apple crisp baked in a Dutch oven. Dinner wine is provided. The nature of a pack in wilderness trip creates limitations on weight. There will be beer, but it is considered a luxury and will be cherished during the trip. You are welcome to BYOB. 

Typical Length of Stay
This deluxe wilderness trip starts with a day and a half horseback ride, and from there covers about 45 miles by raft through the scenic and remote Bob Marshall Wilderness. This is usually a seven (7) day trip, but may be extended.

Non-Angling Activities and Options
While the South Fork is a great angling adventure, non-anglers will no doubt enjoy the trip just as much. Wildlife is abundant throughout the river corridor. Deer, elk, the occasional black bear or mountain goat, eagles and other birds of prey, migratory songbirds search the bushes and the sky for an unsuspecting stonefly. A mid-day hike in the foothills may be rewarded with the treasure of an elk "shed" or deer antler. Although this is grizzly bear country, they are rarely seen. Hiking, eating great food, reading and – above all – relaxing in one of the Lower 48’s most remote places are all important elements of this trip.

Internet / Communications
There is no wireless or cell service in the canyon. Each outfit will have a satellite phone, and/or a US Forest Service radio that can be used to contact rangers in the event of an emergency. If you anticipate needing any communication during the trip it is highly recommended that you rent a satellite phone of your own.


General Information
Fly fishing on the South Fork is known to be some of the best in the world. Due to its wilderness isolation, the river and its tributaries remain lightly fished, and the result is that the quality of the fishery is as good now as it was many decades ago. Skilled anglers can catch over 100 fish per rod on good days, but it is common for each boat to land 40+ native cuts a day. These cutthroat range in size, but there are many in the 12 to 18 inch range, and they love to rise to dry flies!

The South Fork is also one of the only places where an angler can catch the native bull trout. The South Fork Drainage is the largest stronghold of these native Char in the Lower 48 states. These lurkers act like an anadromous species, migrating upstream every July from Hungry Horse Reservoir. Lucky anglers have brought to hand bull trout in excess of 30 inches. Because the South Fork lies within the Bob Marshall Wilderness, special regulations and permits apply. There are only a few commercial outfitting permits on the river, and we are lucky to have an exclusive relationship with one of these outfitters.

Trip Logistics
Trips begin in Great Falls and end in Kalispell. That means that guests need to book their incoming flight into the Great Falls International Airport (GTF) and their outgoing flight out of the Glacier Park International Airport (FCA). Upon arrival in Great Falls, guests are picked up by members of the outfitter and then taken to their chosen hotel accommodations for an overnight stay. The next morning it's off to the trailhead (1.5 hour drive) to meet up with the pack team and start a full day's ride into the first night's camp at Danaher Creek. The next day, it's then a half day ride into Big Prairie where the South Fork of the Flathead is formed. Guests will overnight at this location for the next two nights while walking and wading the South Fork of the Flathead. On the fourth day, the group launches to start the 3.5 day float. On the seventh and final day, the group typically makes it to the take-out point at Mid Creek in the afternoon and then it's a 3 mile walk (1 hour) out the Meadow Creek Trailhead. Upon arrival at the trailhead, everyone is then transferred to their chosen accommodations is Kalispell for an overnight stay, and then it's their responsibility to get themselves to the airport the following day to catch their departure flight for home.




How To Get There
If your plan is to fly to Montana on a commercial airline, we recommend that you make reservations as soon as possible once you have firm river dates. Flights need to be into the Great Falls International Airport (GTF) and outgoing flights out of the Glacier Park International Airport (FCA) which is located just outside of Kalispell.

Arrival and Departure Details / Times
You must schedule a flight that arrives into Great Falls in the afternoon the day before your trip officially begins. The next morning, you will be picked up at your hotel and then taken to the trailhead. The last day of the trip is a big day! You will usually be off the river between 12PM to 1PM, to the trailhead by around 3PM, and then back to your chosen hotel in Kalispell by around 6PM to 7PM. You will need to arrange for a hotel room in Kalispell for the evening on which your trip ends.

Documents Required
Montana fishing licenses are available at all area fly shops and sporting goods stores, or online by visiting the following website: Montana Fish, Wildlife & Parks. You will need to present a valid driver's license in order to purchase your fishing license.
